How does the order of PHP blocks and HTML code affect variable accessibility in PHP?

The order of PHP blocks and HTML code can affect variable accessibility in PHP. Variables must be defined before they are used in PHP code, so if a variable is defined after it is used in HTML code, it may not be accessible. To solve this issue, make sure to define all variables before using them in any HTML code. 

<?php
// Define variables before any HTML code
$name = "John Doe";
$age = 25;
?>

<!DOCTYPE html>
<html>
<head>
    <title>Variable Accessibility Example</title>
</head>
<body>
    <h1>Welcome, <?php echo $name; ?>!</h1>
    <p>You are <?php echo $age; ?> years old.</p>
</body>
</html>
